Why these dates work in zone 8a

Zone 8a's last spring frost averages Mar 25 and first fall frost Nov 10 — about 230 frost-free days. Tomatillo is frost-sensitive, so the 2w after frost timing builds in a safety margin against a late cold snap — setting plants out too early risks losing them to frost. Starting seeds indoors 6 weeks ahead gives strong transplants ready the moment the soil warms.

Will tomatillo survive frost in zone 8a?

No — tomatillo is frost-sensitive. In zone 8a, wait until after the last frost (around Mar 25) to plant, and harvest before the first fall frost (around Nov 10).
